大きな騒音を発する。In other words, compared to changing the selection device from outside air intake to inside air intake, when changing from inside air intake to outside air intake, if the vehicle is traveling at a considerably high speed, the running pressure in the air conditioning duct will be lower. (ram pressure) places a large load on the selection device. For this reason, an electric motor with sufficiently large torque is required. Such electric motors are generally used in combination with a reduction mechanism,
Make a loud noise.

一ヒ記の構成において、この装置の作動を説明すると、
まず手動スイッチ23が外気取入れ用端子25に接続さ

れ用接点21と抵抗27とを介して車載バッテリに接続
される。このため、電 。To explain the operation of this device in the configuration described above,
First, when the manual switch 23 is connected to the outside air intake terminal 25, the electric motor 14 is connected to the vehicle battery via the outside air intake contact 21 of the movable switch mechanism and the resistor 27. For this reason, electricity.

状態を選択する。The movable motor is a movable contact 22 in the movable switch mechanism 18.
The output shaft 16 is rotated until it rotates to the notch at position B'. Therefore, the damper 11 moved by the connecting member 15 of the electric motor 14 selects the outside air intake state shown in the B position.
次に、手動スイッチ23が内気取入れ端子26に投入さ

ンツマ11は電動モータ14によってA位置に示す内気
取入れ状態となる。Next, when the manual switch 23 is turned on to the inside air intake terminal 26, an energizing circuit for the electric motor 14 is formed via the inside air intake contact 20 of the movable switch mechanism 18 and the resistor 28. As a result, the electric motor 14 is supplied with power until the movable contact 22 of the movable switch mechanism 18 reaches the A' position, and the power supply is stopped at the A position. For this reason, the electric motor 14 causes the damper 11 to enter the inside air intake state shown at position A.
この場合、もし自動車の走行速度が基準速度を越えてい

入れから外気取入れへと移行することができる。Therefore, when indoor air intake is commanded by the switch 23 and the car is running at low speed, the electric motor 14
Since it is energized through the resistor 28, it can be operated at low speed and with low noise.
However, when the vehicle is running at high speed, the resistor 28 is short-circuited by the transistor 32 and the diode 33, so that the electric motor 14 rotates at a high speed. Therefore, the damper 11 can shift from inside air intake to outside air intake against the running pressure.
